Nokia and Telefonica of Spain will run DVB-H from September... As commented before, there's no data usage, except the mobile operator being the company in charge of billing for the service and providing support to the technology.

Vodafone here in australia have 500megs of data for $50, at that price point, I would watch it every day.,. and I have downloaded a few cool clips (GPRS is too slow for streaming and telstra is a ripoff) 3 network here have Big Brother LIVE for just $3 a month live steaming video. people buy phones just for that!!!!!!!!

I have tried streaming mp4, WMV and 3gp with my Telecom harrier and it works sweet. so it's kinda cool, however it needs to "on demand though" like run from say 5:30 PM of 7:30 PM so it's like a DVR, if you miss the news you can just catch it on ya mobile. there is no point being stuck in traffic at 6:00 and trying to watch the news there,, Argh!
